UNITED STATES GEORGE W. BENT, OF HYDE PARK, MASSACHUSETTS.

MATTRESS-SUPPORTING FRAME.

Specification of Letters Patent.

Application filed August 5, 1907.

Patented March 16, 1909.

Serial No 387,208.

To all whom it may concern:

Be it knownthat I, GEORGE W. BENT, a citizen of the United States,residing in Hyde Park, in the county of Norfolk and State ofMassachusetts, have invented an Improvement in Mattress-SupportingFrames, of which the following description, in connection with theaccompanying drawings, is a specification, like characters on thedrawings representing like parts.

This invention relates to a mattress-supporting frame provided with amattress-su port, which is secured to the end bars of t e said frame.

The invention has for its object to provide means as will be described,whereby one or both of the end bars are adjustably secured to the sidebars of the frame so as to prevent distortion of the side bars whenstrain is placed u on the mattress-support as will be described.

The invention further has for its object to provide novel means foradjusting the end bars with relation to the side bars when it is desiredto tighten or loosen the mattresssupport.

These and other features of this invention will be pointed out in theclaims at the end of this specification.

Figure 1 is a side elevation of a bed provided with amattress-supporting frame embodying this invention. Fig. 2, a detail inside elevation and on an enlarged scale of one end of themattress-supporting frame shown in Fig. 1. Fig. 3, an end elevation ofFig. 2, looking toward the left. Fig. 4, a plan of Fig. 2, and Fig. 5, adetail to be referred to.

In the present instance I have shown the invention as embodied in ametallic mattresssupporting frame adapted for use with a metallic bed,comprising a head piece or frame a, a foot piece or frame I) andconnecting side rails or bars 0, only one of which is shown.

The mattress-supporting frame comprises parallel side bars or pieces d,only one of which is shown in Fig. 1, and end bars or pieces 6, f, towhich latter is secured in any suitable manner a mattress-support g,which may be the ordinary woven wire mattress or which may be composedof connected links 10 and helical springs 12 (see Fig. 2), or which maybe of any other or suitable construction.

The mattress-supporting frame may be made of metal and the side bars orpieces [I may be metal tubes, while the end bars 6, f, may be made ofangle iron. The present invention has for its object to provide meansfor connecting one or both of the end bars 6, f, to the side bars orpieces (Z in such manner as will permit one or both of said end bars tobe adjusted with relation to the said side bars or pieces, so as to varythe tension on the mattress-support, while at the same time avoidingbowing in or out or other distortion of the side bars or pieces at andmaintaining the latter straight so as to iit the bed frame in thedesired manner.

In the present instance I have shown both end bars adjustable andinasmuch as the connection is the same between the ends of each end barand the side pieces or bars, a detailed description of but oneconnection will suffice to enable the invention to be thoroughlyunderstood.

Reterrim to Figs. 2 to 5 inclusive, the end bar c has firmly secured toit two levers or braces 13, 14, which are shown as joined at their upperends by a cross piece 15 so as to form a yoke, which is fastened to theend bar 6 by rivets 17 (see Fig. 4) or in any other suitable manner. Thelevers 13, 14 straddle the side tube or bar d and are pivotallyconnected therewith at their lower ends by the pivot pin or bolt 20.

The outer lever 13 may have its end eX- tended laterally to form asupporting finger 21, which is adapted to rest upon the side bar 0 ofthe bed frame, and support the mattress frame thereon.

Provision is made for turning the levers 13, 14 on their pivot 20 so asto lower or raise the end bar 6 with relation to the side bar or piece(1 and thereby place more or less tension upon the mattress-support g,and this result may be accomplished as herein shown by means of anadjusting screw or bolt 22 eX- tended up through the side bar or piece(Z and provided with a nut 23 having arms 24, which are engaged by linksor hooks 25 whose upper ends are bent to enter holes 26 in the end bar.The lower end of the bolt 22 may be curved to form a handle 28 and tosupport a washer 29, which engages the underside of the bar d. The linksor hooks 25 may be provided with heads 30 to prevent their disengagementwith the nut.

By turning the bolt 22, the nut 23 is caused to travel thereon andthereby through the links 25 effect movement of the end bar c withrelation to the side bars d, which is permitted by the pivot 20 for thelevers 13, 14. It will be observed that the mattress spring support 9places a very considerable strainv upon the levers 13, 14, which strainis transmitted equally to the opposite sides of the side bar or piece01, and buckling, bowing or distortion of said Side bar laterally withre: lation to the side bar 0 of the bed frame is prevented, therebypreserving the side bar (1 in its proper and desired parallel relationto the bed frame.

I have herein shown one construction of mattress-supporting frameembodying this invention, but I do not desire to limit the in.- ventionto the particular construction shown.

laims.

1. In a mattress-supporting frame, in com-v bination, side bars, endbars, a mattress-support secured to said end bars, levers secured tosaid end bars and pivotally connected .to. the said side bars onopposite sides thereof, one of said levers having a laterally extendedfinger to rest on a side rail of the bed frame, a bolt extended throughthe side bar, a nut on said bolt, and a link connecting said nut with anend bar, substantially as described.

2. In a mattress-sup ,olting frame, in combination, side bars, enc bars,a mattresssupport rigidly secured to said end bars, upwardly inclinedlevers pivoted at their lower ends to the opposite sides of said sidebars and secured at their upper ends to. one of'said end bars, and meansfor adjusting said end bar with relation to said side bars, said meansbeing connected with said end bar and with a side bar at the rear of thepivot for said levers, substantially as described.

3. In a mattress-supporting frame, in combination, side bars, endbars, amattress-support secured to said end bars, levers secured to said endbars and pivoted to said side bars, said levers having laterallyextended fingers to rest upon a side rail of the bed frame, and meansfor adjusting said end bars with relation to said side bars,substantially as de- .for pivotally connecting one of said end bars tosaid side bars, and means for adjusting said end bar with relation tosaid side bars, and comprising a bolt extended through the side bar andcapable of rotation, a nut on said bolt, and a link connecting said nutwith said end bar, substantially as described.

5. In a mattress-supporting frame, in combination, side bars, end bars,a mattress-sun port rigidly secured to said .end bars, means forpivotally connecting one of said end bars to said side bars, means foradjusting said end bar with relation to said side bars, and comprising abolt extended through the side bar, a nut on said bolt, and meansconnecting said nut with relation to said end bar, substantially asdescribed.

6. In a 111attress-supportingframe, in 'combination, side bars, endbars, a mattress-support rigidly secured to said end bars, leverssecured to one of said end bars and pivoted to said side bars, and meansfor adjusting said end bar with relation to said side bars, said meanscomprising rotatable devices connected with the side bars andnon-rotatable devices connected with the end bar, substantially asdescribed.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
